Cats bitten by a C. felis-infected tick become extremely
ill within 1-3 weeks. Because C. felis affects many organ
systems - blood, the liver, lungs, the spleen, and lymph
nodes - symptoms of Cytauxzoonosis include sudden
listlessness, loss of appetite, anemia, difficulty breathing, high
fever, and jaundice. Even with proper veterinary diagnosis
and treatment, recovery from Cytauxzoonosis is rare.

Until recently, no treatment for Cytauxzoonosis has proven
consistently effective. Certain antibiotics and anti-protozoal
drugs continue to show promise. Intravenous fluids and
other supportive care are also necessary. Because cats
who recover from Cytauxzoonosis may still carry the
parasite and suffer recurrence, prevention is essential.
